MANUFACTURE or ARTlElClAL STONE AND MARBLE.

SPECIFICATION forming part of Letters Patent No. 268,535, dated December. 5, 1882.

Application filed September 21, 1882. (No specimens.)

Manufacture of Artificial Stone and-Marhle; and I hereby declare the-following tobe a full,

clear, and exact description thereof.

M y invention relates to an improvement in to the manufacture of artificial stone and marble, whereby a beautiful imitation of natural stoneor marble can be produced at a small cost, possessing the necessary strength, hardness, and durability to adapt it. for use as a building material in any climate, and for a variety of other purposes; and my invention consists in a composition formedof certain ingredientscombined and chemically treated in such a manner as to produceahard. c'ryszo tallized and carbonized substance which is impervious to water, and will successfully resist the action of frost and heat, as hereinafter set for t-b.

In carrying my inventiouinto efl'ect I take a suitable vessel and place therein torty-six add thereto one pound gallons of water and of pulverized Blacklcad, one quart of silicate paint, (a natural liquid paint foun in t e mountains of-Wales, and commercially known as petrified liquid two quarts of strong lime-W 1 on'e-l'ial f pound of'carbonate of soda and one-halfpound ofborax. he whole is en thoroughly mixed and incorporated together by stirring until the soluble ingredi- To make artificial stone for buildingsand other purposes, 1 mix thoroughly, in a dry state, one part of cement (preferably Alsen 8: Sous"Ge-rman cementi and five parts of 4.0 clean sharp sand or gravel, more or less, andthen dampen this mixture witha sufficient quantity of the above-described chemical solution, after which it is tam ped or pressed into molds of any desired form or shape in the ordinary manner.

To manufacture'artificial marble I takea suitablequantity of the above-described chemioalsolution and'add thereto Keenes em t,- which should be mixed with white sander o marble-dust, and thoroughly stir and 1"ncorporate the whole together until the mass assumes the consistence of a thick paste, when it is placed insnitable molds to' give it the desired shape and compressed, after which it is allowed to 'remain' for about six hours, or until hard and dry, when, after removal, it can be polished in the same manner as natural marble. r e The above-described composition may be made of any color desired by the addition of the necessary pigmeut,'and colored or variegated marble may be imitated by the employment of-difl'erent pigments or colors, which are added to the paste and mingled or manipulated in awell-known manner to produce the desired imitation of the veins or figures ol'natural marble, the blocks or other, articles made of this material presenting, when finished, a beautifulappearance, and hearing a perfect resemblance to natural marble.

The chemical solution above described procauses-the entire mass to become crystallized, solidified, and hardenedto such an extent that it will be impervious to air, will effectually rc-- p'elwater, and withstand, without injury, the action of frost, fire, or otherdisintegrating or climatic influences.

Artificial stone and marble made as above described may be employed to great advantage for building-blocks, monuments and other cemetery work, sidewalks, sewer-pipes,-welltubing, mantelpieoes, and generally for the interior and exterior decoration of buildings, flooring, coating ofinner'and outer walls of buildings, slabs for tables, and other articles articles, it being easily and cheaply molded into any desired shape, whereby an immense which is incurred incutting natural stone or .marble into the great variety of elaborate designs commonly used is entirely avoided.

What I claim as my invention, and desire to secure by Letters Patent, is-
